Purpose: To examine the association between changes in objectively measured overall physical activity (PA), with changes in fasting and postprandial plasma insulin, C-peptide and glucose concentrations, in type 2 diabetes prone Pakistani immigrant men living in Norway and to examine whether this association is explained by changes in moderate-and-vigorous PA (MVPA) ...
Abstract: The etiology of type 1 diabetes (T1D) remains unknown, but a growing body of evidence points to infectious agents and/or components of early childhood diet. The National Institutes of Health has established the TEDDY Study consortium of six clinical centers in the United States and Europe and a ...
Purpose: Physical activity declines dramatically during adolescence and activity levels are consistently lower among children living in low-income communities. Competency in a range of fundamental movement skills (FMS) may serve as a protective factor against the decline in physical activity typically observed during adolescence. The purpose of this study was ...
Background/Purpose: It has been shown that pedometer-based physical activity interventions are an effective means to promote increases in daily ambulation (steps/day). It is not known however at what cadence (steps/min) participants accumulate more steps in as a result of such interventions. Therefore, the purpose of this study ...
Purpose: This study compared sitting, standing, and stepping classifications from thigh-worn Actigraph and activPAL monitors under laboratory and free-living conditions. Methods: Adults wore both monitors on the right thigh while performing six sitting, two standing, nine stepping, one cycling activity, and writing on a whiteboard with intermittent stepping under laboratory ...
Purpose: The purposes of this study were (1) to add layers and features to a previously published fully automated algorithm designed to identify children's nocturnal sleep and to exclude episodes of nighttime non-wear/wakefulness and potentially misclassified day time sleep episodes, and (2) to validate this refined sleep algorithm (RSA) against sleep ...
Abstract: Research has shown that current smokers have a lower mean body mass index (BMI) than never and former smokers, with former smokers having the highest mean BMI. A number of physiologicalmechanisms have been hypothesized to explain this pattern, but few studies have explored the possible role of behavioral factors. ...
Abstract: This study examined the feasibility of reducing free-living sedentary time (ST) and the convergent validity of various tools to measure ST. Twenty overweight/obese participants wore the activPAL (AP) (criterion measure) and ActiGraph (AG; 100 and 150 count/minute cut-points) for a 7-day baseline period. Next, they received a simple intervention ...
Abstract: Simple methods to quantify ground reaction forces (GRFs) outside a laboratory setting are needed to understand daily loading sustained by the body. Here, we present methods to estimate peak vertical GRF (pGRFvert) and peak braking GRF (pGRFbrake) in adults using raw hip activity monitor (AM) acceleration data. The purpose ...
Background: Patients undergoing bariatric surgery do not seem to increase objectively measured physical activity (PA) after surgery, despite substantial weight loss. The aims of the present study were (i) to objectively characterize 3 months pre-surgery to 9 months postsurgery PA and sedentary behavior changes in women undergoing Roux-en-Y gastric bypass (RYGB) using ...
